Rexroth Solution:

Variable-speed pump drives

Variable displacement pumps

Combined electro-hydraulic systems

Key Insights & Considerations:

  • Electro-hydraulic systems combine the advantages of both traditional hydraulics and electric drives, including robustness, power density, drive intelligence and ease of integration with factory automation systems
  • Variable-speed pumps and drives reduce energy demand and improve efficiency
  • Internal gear or piston pumps provide high efficiency, low flow ripple, low mechanical inertia and high pressure
  • Axial piston pumps have high efficiency at low drive speeds
